This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own 💭Dream Car Collection [LUCK EVENT] session. It will not click the shop.
Upgrade payback
Upgrade payback
Estimate how many income cycles a cash upgrade needs before it repays its price. Type the live cost and the extra income you expect. The sample numbers are not taken from the game.
Payback cycles = upgrade cost ÷ extra profit per cycle, rounded up.
100000, 50, and 1 are sample inputs so the form can run. They are not Dream Car Collection prices. Read the next level's cost on the Upgrades station and estimate the extra cash from your own wall. The form divides cost by extra income per cycle. It does not apply the 12-hour wash boost, rebirth multipliers, Offline Cash, gems, or the October 10 drive-world changes unless you already folded those into the numbers you type.
Drop probability
At least one success
Turn a percentage you can see on your own client into the chance of at least one success over several opens. Do not type a number you found outside the game. No public odds table exists.
Chance of at least one success = 1 − (1 − chance per attempt) raised to the number of attempts.
10 and 5 are form samples, not crate odds. Dream Car Collection has no published drop table. Use this only when your client actually shows a percentage. The result is the chance of at least one success across independent attempts. It does not model pity, luck potions, or crate tiers.
